Laboratory Staff

Samuel R. Barber, MS


Samuel R. Barber, MS, is a fourth-year medical student at Tufts University School of Medicine. He joined Dr. Daniel Lee's lab to take dedicated time off for research as part of the Tufts Research Concentration Program (RCP). Prior to medical school, Sam was a surgical neurophysiologist, performing intraoperative neuromonitoring in surgical procedures of the spine for conditions such as congenital or degenerative scoliosis, metastatic tumors, and tethered spinal cords. Currently, Sam is the clinical coordinator for FDA device trials investigating Auditory Brainstem Implants (ABI) in non-neurofibromatosis type 2 patients and cochlear implants for single sided deafness. His research focus includes investigating the relationship between audiometric data and ABI electrode position using analysis of post-processed CT imaging techniques, along with design and fabrication of 3-D printed surgical simulators.

Maria J. Duarte


Maria J. Duarte is a fourth-year medical student at Harvard Medical School (HMS). She joined the Lee/Brown Lab for her research year as part of the HMS five-year medical degree track. Prior to medical school, Maria graduated summa cum laude from the University of Florida with degrees in biology and anthropology. She has previously been involved in research on hypoxic injury using an in-vitro model for ischemic-reperfusion injury and the role of hydrogen sulfide as a signaling molecule in the mTOR pathway. She has also conducted original clinical research on the outcomes of interdisciplinary trauma patient care. Currently, Maria is investigating novel approaches to optogenetics-based next generation cochlear and auditory brainstem implants, is helping to build and coordinate Mass. Eye and Ear’s database on Superior Semicircular Canal Dehiscence, and conducts clinical investigative work in this area. 

Vivek Kanumuri, MD


Vivek Kanumuri, MD, is a resident-physician in otolaryngology—head and neck surgery at the Mass. Eye and Ear/Harvard Medical School. Originally from Edison, New Jersey, he graduated from Rutgers University - New Jersey Medical School in 2014 with a medical degree and was elected into the Alpha Omega Alpha honor society. During his time in medical school he also completed a prestigious Howard Hughes Medical Institute Research Fellowship where he worked on multiphoton imaging and optical manipulation of epileptic circuits under the mentorship of Dr. Rafael Yuste at Columbia University. He is currently working in the Auditory Brain Implant Lab with Dr. Daniel Lee on the development of optical neuro-prosthetics for stimulation of the auditory system as part of the T32 grant in the Eaton-Peabody Laboratories at Mass. Eye and Ear. He also has clinical interests and has published extensively on endoscopic skull base surgery and sinonasal malignancies.

Elliott D. Kozin, MD

Elliott KozinElliott D. Kozin, MD, graduated summa cum laude from the University of Pennsylvania with a degree in history prior to receiving his medical degree at the University of Pennsylvania School of Medicine. During medical school, he spent a year at the National Institutes of Health (NIH) in Dr. Bechara Kachar's laboratory investigating the role of non-muscle myosin II in the inner ear as part of the Howard Hughes Medical Institute Research Scholars program. As one of the seven-year research track residents at Mass. Eye and Ear/Harvard Medical School, his current research with Dr. Daniel Lee focuses on employing optogenetics to improve cochlear and auditory brainstem implant technology.

Osama Tarabichi, MD


Osama Tarabichi, MD, received his medical degree from the Royal College of Surgeons in Ireland-Bahrain. He developed an interest in hearing sciences early on in his medical school career and spent his summers at the Auditory Research Laboratory at St. Louis University studying oxidative stress signalling in the lateral wall of the cochlea. After graduating medical school, he decided to pursue a research fellowship at the ABI lab. His research at Dr. Daniel Lee's Lab is focused on developing a chronic mouse model of the auditory brainstem implant.

Kevin Wong

Kevin Wong

Kevin Wong is a medical student in the accelerated seven-year BA/MD program at Boston University's School of Medicine. Kevin has been interested in medical research since high school and has continuously sought out opportunities to enrich his own training. As an undergraduate student, Kevin completed a six-month clinical research fellowship with a lung transplant team under Allan Glanville, MBBS, MD, FRACP, at the University of New South Wales in Sydney, Australia. His training has continued in medical school with a summer research fellowship with the Foundation for Anesthesia Education and Research where he learned to create and coordinate quality improvement projects. Kevin recently completed his third year of medical school and is now dedicating a full year to continue research pursuits within otolaryngology. Currently, Kevin coordinates the Mass. Eye and Ear/Mass General Hospital pediatric auditory brainstem implant FDA trials. His other research interests include medical applications of augmented reality and medical education.
